Serial No. 253,534. (No modeLl' To aZZ whom it may concern.-

Be it known that I, HERBERT J. HARWOOD, a citizen of the United States,residing at Littleton, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inProjectiles for Fire-Arms; and I do declare the following to be a full,clear, and exact description of the invent-ion, such aswill enableothers skilled in the art to which it appertains to make and use thesame, reference being had-to the accompanying drawing,and to the lettersand figure of reference marked thereon, which form a part of thisspecification.

My invention consists in making aprojectile for fire-arms in two partsor portions and of different metals, and connecting them with eachother, as hereinafter described,its pointed or the conoidal portion ofit being made of steel or some other hard metal joined to a body made oflead or other metal, which is to be sufficiently soft to enter thespiral grooves in the barrel of the piece while in movement therein, andthereby cause-the projectile when expelled therefrom to rotate.

In the drawing, the figure shows asectional View of my invention.

In constructing this projectile the portion A, after having been forgedor swaged into the required shape, is placed in a mold, the shank a ofit projecting into the space in the mold, into which the soft metal in amolten state is to be poured around the said shank a, so as to form thebody portion B, the exterior surface of which is formed with concentricribs 0, 5

which are to extend into the spiral grooves in the interior surface ofthe bagel of the firearm. Instead of casting the soft metal around theshank and against the shoulder of the part A, it can be pressed intocontact therewith.

The advantage of making a projectile as described is, that in providingit with a steel or hard-metal point its penetrating power is very muchincreased, it having been demonstrated that a projectile so made willpenetrate atar- 5 get or objectmore than twice the distance that anordinary lead projectilewill, and it can also be thrown with a greaterdegree of accuracy than the ordinary bullet, for the reason that itsforemost end is more perfectly constructed,- and will retain its shapeand will rotate to bet ter advantage than aleaden bulletor projectile.

Having described my invention, what I claim, and desire to secure byLetters Patent,

A projectile for fire-arms, consisting of the conoidal portion A,provided with the shank (1, having extending from its surface one ormore ribs, 1), concentric therewith, in combination with the part B,provided with the ribs 0 a, substantially as shown and described.

In testimony whereof I affixmy signature in presence of two witnesses.
